How do you make peace with what you can't control
Recently, I had a mental breakdown because I was organizing a film project and the friend who was with me wasn't excited about it at all. He didn't seem to care, and I started to feel completely depressed because it honestly killed my motivation to do the project at all.
After that, I made a list of everything I hate in life because there’s a fucking lot. I was talking to a friend who said that in life, I need to adapt because the world isn't going to adapt to me. I think he is right because I’m realizing more and more that my problems with the world are often things I can't control that are bugging me, and I’m just not able to be at peace with them.
How do you make peace with things you can't control? I know you just need to accept it, like Stoics normally say, but I don't want to.
